It is not possible for us to tell you whether your child is one that would be harmed by early weaning. The important question is would your child be harmed by waiting to wean?
My cousin (and very good friend) has a little boy who is 7 months who had/has silent reflux to answer your question. I therefore cannot comment on silent reflux with any authority whatsoever.
My dd who didn't have any silent reflux/allergies/intolerances and in fact was and is extremely robust fed at least every 2hrs, slept badly, needed lot of attention, chewed her hands, dribbled. All normal. She went through a growth spurt around 4/5 months that lasted a few weeks and was a lot of hard work. I always took the view that I might not be able to change the baby I was given, nor would I want to but I could make every conceivable change to make my life easier so asking for help, sleeping whenever I could, ignoring the housework etc.
Like I said only a medical professional can advise you on whether there is a medical need to wean your child early.
I do sympathise. I cannot imagine doing it with an older child too. It's a lot of hard work.
